Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA Cross-Site Request Forgery (CSRF) vulnerability exists in the Zalo Official Live Chat plugin (versions <= 1.0.0). The plugin fails to properly validate the origin of requests, allowing attackers to trick authenticated users into performing unintended actions such as sending chat messages or modifying settings. This is a standard CSRF attack vector exploiting the lack of anti-CSRF tokens in the plugin's forms and AJAX actions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed plugin versionLocate the Zalo Official Live Chat plugin in your CMS/plugin directory and read the version information from the plugin header file (typically version.txt, readme.txt, or the main plugin PHP file). Compare it to the affected range: versions 1.0.0 and below are vulnerable.Affected if The installed version is 1.0.0 or any earlier version of the Zalo Official Live Chat plugin.
-
Inspect plugin forms for CSRF tokensExamine the HTML source of all state-changing forms rendered by the plugin (e.g., settings forms, message sending forms). Look for a hidden input field containing a token value (commonly named '_wpnonce', 'csrf_token', 'nonce', or similar) within each <form> tag.Affected if No anti-CSRF token field is found in the plugin's HTML forms.
-
Inspect AJAX endpoints for nonce verificationReview the plugin's PHP source code that handles AJAX requests (typically in the main plugin file or dedicated AJAX handler files). Search for calls to nonce verification functions (e.g., 'check_ajax_referer', 'wp_verify_nonce', or equivalent validation logic) before processing state-changing requests.Affected if AJAX handlers lack nonce verification or the verification is missing/disabled.
-
Check Referer/Origin header validationExamine the server-side PHP code that processes form submissions and AJAX requests. Look for validation of the HTTP Referer or Origin header to confirm the request originated from your legitimate site.Affected if No Referer or Origin header validation is performed on state-changing requests.
-
Verify SameSite cookie configurationInspect the session cookie or authentication cookie settings used by the plugin. Check if the SameSite attribute is set to 'Strict' or 'Lax' on cookie definitions.Affected if Cookies related to the plugin lack SameSite attribute or have it set to 'None' without Secure flag.
You are affected if the Zalo Official Live Chat plugin version is 1.0.0 or lower AND the plugin's forms lack CSRF tokens, AJAX endpoints lack nonce verification, and no Referer/Origin validation exists.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement anti-CSRF tokens (synchronizer token pattern) on all state-changing forms and AJAX endpoints, and validate the Referer/Origin header on server-side requests. Additionally, configure the SameSite attribute on session cookies.
